I WILL GIVE YOU 100 points and Braine at Math Properties of Equality, Part 2
For each expression, write an equivalent expression to show the
mathematical properties of equality.
Distributive Property:
6(m +4) = ?
Associative Property:
2 + (m + x) = ?
Commutative Property:
x + 3 = ?
Distributive Property:
3(2y - 6) = ?
Distributive Property:
m(y + 5) = ?
Answers
Answer:
1. 6(m + 4) = 6m + 24
2. 2 + (m + x) = (2 + m) + x
3. x + 3 = 3 + x
4. 3(2y - 6) = 6y - 18
5. m(y + 5) = my +5m
Step-by-step explanation:
1. Distributive property "distributes"/multiplies the 6 outside the parentheses to each term inside the parentheses.
2. Associative property deals with how terms and numbers are grouped into parentheses. The terms/numbers stay in the same order.
3. The commutative property means terms can change in order, and you will still get the same result.
4, 5. See #1 above. Distribute/multiply the number/term outside the parentheses to the numbers/terms inside.

Determine whether the sequence converges or diverges. If it converges, find the limit. [Hint:
consider limit laws, the Squeeze Theorem, behavior of related real-valued functions, etc.]
(a) an = 2 + (0.86)^n
(b) an =(4^n)/(1+9^n)
(c) an = arctan(ln n)
Answers
(a) converges; consider the function f(x) = a ˣ, which converges to 0 as x gets large for |a | < 1. Then the limit is 2.
(b) converges; we have
4ⁿ / (1 + 9ⁿ) = (4ⁿ/9ⁿ) / (1/9ⁿ + 9ⁿ/9ⁿ) = (4/9)ⁿ × 1/(1/9ⁿ + 1)
As n gets large, the exponential terms vanish; both (4/9)ⁿ → 0 and 1/9ⁿ → 0, so the limit is 1.
(c) converges; we know ln(n ) → ∞ and arctan(n ) → π/2 as n → ∞. So the limit is π/2.

Answers
Answer:
hello your question is incomplete below is the complete question
A company's human resources department was interested in the average number of years that a person works before retiring. The sample of size 11 follows: 12 16 18 19,21 21, 21,22 24 24 26What is the arithmetic mean, median and mode? what is the most likely shape of the distribution
answer :
i) mean = 20.36
ii) median = 21
iii) mode = 21
iv) The most likely shape is a Bell - shaped curve
Step-by-step explanation:
sample size = 11
values ( observations ) = 12, 16, 18, 19,21,21,21,22,24,24,26
i) mean
= ∑ values / sample size = 224 / 11 = 20.36
ii) median
median is the value of the data located at the center of the string of data
to determine the middle position = ( n+1 / 2 )
where n = sample size
hence position of median value = 11 + 1 / 2 = 12 / 2 = 6
the value at the 6th position = 21 ( median )
iii) mode
mode = most repeated value in the series of data
hence mode value = 21

Answers
Answer:
x = 8
y = 14
Step-by-step explanation:
2x + 6 = 4x - 10 (Corresponding angles so they're equal)
2x - 4x = -10 - 6
-2x = -16
x = 8
2x + 6 + 13y - 24 = 180 (Supplementary angles so they add up to 180)
2(8) + 6 + 13y - 24 = 180
16 + 6 + 13y - 24 = 180
13y - 2 = 180
13y = 182
y = 14
Answer:
2x+6=4x-10[corresponding angle]
16=2x
x=8
again
2×8+6+13y-24=180°[linear pair]
13y=180+2
y=182/13
y=14

Hank has 4 green marbles for every 9 red marbles. If hank has 39 total marbles, how many green marbles does he have? pls answer ASAP it for assignment
Answers
Answer:
12 green marbles
Step-by-step explanation:
in this case we have to add the the green marbles as 4 and red marbles as 9
so, 4 + 9 = 13 and divide the total marbles to it
so, 39/13 = 3
so, here we have 3 times marble in 13 green marble to get the total number
so, 3 (13)
so, in this case we have to separate the green and red
so, 13 as ( 9 red + 4 green)
so,3 times ( 9 red + 4 green)
in this case we can use distributive property of multiplication
so, 3 times 9 red = 27 is the total red marbles
and 3 times 4 green = 12 is the total green marbles
to check the answer we have to add this two
so, 27 red marbles + 12 green marbles = 39 total marbles
so, that's why it is 12 green marbles

The area of a triangle is 1/2 x base x height.
The area of the triangle is 1/2 x 6 x 8 = 24 square cm.
There are 4 identical triangles so 24 x 4 = 96 square cm.
The area of the square base = 6 x 6 = 36 square cm.
Total area = 96 + 36 = 132 square cm.
